Vicor introduces high-performance MIL-COTS DC-DC converters


The DCM VIA family are ruggedised modular DC-DC converters in a thermally adept, low profile (9.3 mm) VIA package, with wide input voltage range specifications and isolated, regulated high efficiency outputs.

This new DC-DC converter range features enhanced functionality and performance, including EMI filtering, transient protection, inrush current limiting, as well as a secondary-referenced control interface for trim, enable and remote-sensing, according to the manufacturer.

Two new MIL-COTS (M-Grade) versions are available now, with 270V (160 – 420V input voltage range) DCM 3714 VIA family and nominal output voltages of 24V and 28V with up to 500 Watts of output power.

Complementing these high voltage MIL-COTS DCM VIA’s is a new MFM 270V filter module (MFM filter).  This  dense, low-profile filter provides front-end transient protection and EMI filtering when used with any Vicor M-Grade 270V DCM 3714 VIA module. This combination enables power engineers to rapidly meet conducted emissions and conducted susceptibility requirements per MIL-STD-461E/F and input transients per MIL-STD-704F. The MFM 270V filter module is housed in a 1714 VIA package (size: 1.76” x 1.40” x 0.36” / 44.6 mm x 35.5 mm x 9.3 mm), accepts an input voltage of 160 – 420 VDC and can deliver up to 640 Watts of power.
